FIELD: building.
SUBSTANCE: invention relates to the field of building, namely, to methods for manufacturing three-dimensional building blocks of varying geometry using removable formwork. The method consists in interconnecting the formwork elements, closing the internal volume from all sides. The shape of the inner surface of the formwork is set, and a settable compound is fed into the volume. After the product reached the strength sufficient for removal thereof from the mould, the product is removed by detaching the formwork elements. A lower plate installed on the assembly table, side elements installed with the end surfaces thereof on the lower plate along the perimeter, and an upper plate laid on the end surfaces of the side plates opposite to the end surfaces in contact with the lower plate, are therein used as formwork elements. At least one element of the mould therein comprises at least one shaping surface. The settable moulding compound is poured into the closed mould volume. The volume of the poured compound is therein greater than the volume of the material of the finished product in the range from 1 to 65%, preferably from 5 to 15%, and most preferably 10%. A pressure of at least 9 kPa is applied to the settable compound in the mould by introducing at least one submersible element and fixing until the product reaches the strength sufficient for removal thereof. The filling mould comprises at least one channel, the cross-sectional shape whereof relative to the axis passing through the centres of the channel base in the central part thereof is selected from a group consisting of a circle, oval, square, rectangle, triangle, trapezoid, or combinations thereof, intended for introducing the submersible element, in the course of submersion whereof the required pressure of the compound is created in the closed mould volume. The settable compound is held. After the strength sufficient for removal is reached, the resulting product is removed by detaching the mould elements.
EFFECT: increase in the quality of monolithic concrete blocks with improved strength characteristics and stability of the geometry in batch production.
